Domain Name Server (DNS)

A domain name server (DNS) converts domain names into Internet protocol (IP) addresses. Domain name servers can be thought of as the Internet's equivalent of a phone book. As they maintain a directory of domain names and translate them into IP addresses, these mappings allow a computer to locate a website and a user to access a website.

One domain name server example is the domain name www.whitehatsec.com. Through DNS, it is converted to the IP address 64.62.160.186.
